The pH of concrete washout from construction and building sites is highly caustic (pH 12-14) which makes it extremely damaging to the environment if discharged into the watercourse (River or Sea). The Environment Agency stipulate it is illegal to discharge above an acceptable level of between pH 6-9.The same applies to concrete wagon washout to sewers or surface drains controlled by Water Companies where it is illegal to discharge below pH 6 and above pH 10.Failure to comply may lead to substantial fines and even plant/site closure.Because pH is a log10 scale it is not practical to simply dilute the washouts with clean water as 10,000 litres of water would be required to get 1 litre of water down from pH 13 to pH 9.
